This result uses the ActionMapper provided by the
ActionMapperFactory to redirect the browser to a URL that invokes the
specified action and (optional) namespace. This is better than the
ServletRedirectResult because it does not require you to encode the
URL patterns processed by the ActionMapper in to your struts.xml
configuration files. This means you can change your URL patterns at any point
and your application will still work. It is strongly recommended that if you
are redirecting to another action, you use this result rather than the
standard redirect result.

See examples below for an example of how request parameters could be passed
in.
